# SIFR-LINT-0003: Suppression must list explicit Sifr policy rule ids.

> Suppression must list explicit Sifr policy rule ids.

`SIFR-LINT-0003` belongs to the **Policy linting** diagnostic family. It means: suppression must list explicit Sifr policy rule ids.

## Why It Happens

A suppressible policy rule fired, or a suppression itself is malformed. Fix the policy issue or make the suppression exact and local.

<Info>
  Use `sifr --explain SIFR-LINT-0003` locally to see the renderer's exact message template and any machine-applicable suggestions for the compiler version you are running.
</Info>

## Erroneous Code

```python theme={null}
# sifr: ignore
def f(flag: bool):
    pass

f(True)
```

## How To Fix It

Fix the policy issue when possible. If suppression is intentional, list the exact policy rule id and keep it local.

## Fixed Code

```python theme={null}
# sifr: ignore SIFR-LINT-0006
def f(flag: bool):
    pass

f(flag=True)
```
